5. Young Lady and Gentleman
And does it have to be the whole family? Can it just be a couple members, or what if that is the only family left?
6. Unforgotten Night - that one woman who works for the one guy lives with her son in his house - I think, not 100% sure cause I dropped it.
7. Maid's Revenge - FL moves in as a maid, but the rest of her family is dead except for her half-sister, who lives there, too. (I don't think this is a spoiler as it is in the description.)
